CW 2. March 21,2023, ME 330, Sec AL1, Z 1. Your name On the isothermal transformation diagram for a 0.45 wt% C, Fe-C alloy, sketch and label the time-temperature paths to produce the following microstructures: a) 50% fine pearlite and 50% bainite b) 100% martensite c) 50% martensite and 50% austenite 800 Austenite (stable) T(C) A 600 P 100% pearlite 100% bainite TE 2. B 400 A 200 10-1 10 -0% 100% -50% 103 105 time (s) Adapted from Fig. 10.18, Callister & Rethwisch 8e. Rank the following iron-carbon alloys and associated microstructures from the highest to the lowest tensile strength: 0.25 wt% C with spheroidite 0.25 wt% C with coarse pearlite 0.60 wt% C with fine pearlite 0.60 wt% C with coarse pearlite Justify this ranking.
